Cross-border enforcement

Enforcing a Luxembourg judgment in Germany

Brussels Ia applies. Luxembourg and Germany are both EU member states bound by Regulation 1215/2012, so a Luxembourg judgment is recognised in Germany without any German court first declaring it enforceable. Enforcement itself still needs a certificate issued by the Luxembourg court and separate steps taken in Germany. The regime works, but only for judgments that actually fall within its scope.

Applicable regime

The controlling instrument is Regulation (EU) No 1215/2012, Brussels Ia. Between EU member states it replaces the older exequatur model: a judgment given in Luxembourg is recognised in Germany without a German court first declaring it enforceable. Both the Luxembourg and German sides of this route confirm that judgments moving between member states travel this way. This page sits within a wider set of enforcement routes into Germany from different origin states, and the routes differ by origin, not just by destination.

Brussels Ia only covers judgments that fall within its own material scope. Where a Luxembourg judgment sits outside that scope, the applicable instrument becomes the Hague Judgments Convention 2019, in force for the EU, including both Germany and Luxembourg, since 1 September 2023. Which instrument governs a given judgment depends on the nature of the underlying proceedings, not on either party's preference.

What the destination court will check

The authority responsible for enforcement, determined by the applicable procedural rules rather than by choice, checks a defined set of formal conditions before enforcement proceeds. They apply cumulatively, not as alternatives:

• The decision is a judgment within the meaning of the Regulation, issued by a Luxembourg court in a civil or commercial matter.
• The judgment is enforceable in Luxembourg at the point enforcement is sought in Germany.
• The applicant produces the certificate issued by the Luxembourg court together with a copy of the judgment.
• The certificate has been served on the debtor before enforcement measures go ahead.

None of these steps require a German court to re-examine the merits already decided in Luxembourg. The check is procedural.

What will not go through

Judgments outside the civil and commercial scope of Brussels Ia do not travel on this route. A judgment not yet enforceable in Luxembourg, because an ordinary appeal is still pending there, does not travel either, at least not on final terms.

A recurring trap is a default judgment where service on the debtor is disputed. Brussels Ia removes the general exequatur requirement, but it does not remove every objection a debtor can raise about how the original proceedings were conducted. The refusal mechanics that apply to that kind of objection are covered separately under non-enforcement grounds.

Documents

Germany accepts apostilled documents under the 1961 Convention, in force there since 13 February 1966. For a judgment moving under Brussels Ia specifically, the certificate and judgment copy pass between the two courts without a separate legalisation chain, because the Regulation governs how they circulate. Documents not already in German will still need translation; the exact form the enforcing court requires is not something we hold a standardised figure for. Further background on how this fits the wider procedural picture sits on the Germany jurisdiction profile.

Timing

German law gives a claim already confirmed by a judgment thirty years to be enforced, running from the point the judgment became final. Taking the steps needed to enforce it in Germany interrupts that period; it does not keep running quietly in the background once enforcement is under way.

We do not hold a verified figure for how long the German enforcement stage itself takes once the certificate is filed. That depends on the court's docket and on how the debtor responds. Limitation periods differ sharply by jurisdiction, and a broader comparison sits on our limitation periods across jurisdictions page.

If the primary route is closed

If a judgment falls outside Brussels Ia's scope, the Hague Judgments Convention 2019 is the next instrument to check, given its entry into force for the EU covering both Luxembourg and Germany. Where the underlying dispute could instead have gone to arbitration, an award enforced under the New York Convention 1958 reaches a wider set of states than any judgment-based route can.

We set out how a convention route compares against a purely national one in this comparison of convention and national enforcement. The same debtor may also hold assets reachable by enforcing somewhere else first; outbound enforcement from Luxembourg and the reverse Germany-to-Luxembourg direction are separate questions, covered respectively on enforcement from Luxembourg and Germany to Luxembourg.

What to do before filing

Check where the debtor actually holds assets that Germany can reach. A Luxembourg judgment recognised on paper is worth little against assets that have already moved elsewhere, and Luxembourg-domiciled entities can shift bank balances and shareholdings faster than a certificate can be issued.

Whether an interim measure can address that risk before enforcement formally starts depends on the specific facts of the case; we do not give a general answer here. Filing also carries its own risk for the applicant: an unsuccessful attempt can leave costs exposure on top of the original loss. An initial assessment, priced separately from any later enforcement work, maps the asset picture before anything is filed; it is described under cross-border recognition and enforcement.

We charge no fee contingent on recovering the judgment, and our registration can be checked in the public register linked in the footer.
